The Park continues to fish well, particularly if you're able to hike in and escape the crowds. We're getting to that time of year where pretty much all of the easily accessible stuff near and around the trailheads and roads has seen a good pounding. The wild trout in the park are opportunistic, but the fish that see flies every day during peak vacation season can get a little wary. Getting out on a week day is always a good idea too, if you can. Hatches we've seen include PMDs, caddis, drakes, stones, sallies, terrestrials -- in other words, the bugs are out and the fish are feeding. The overall trend of overcast, relatively cool weather we've experienced in the region lately has produced some awesome dry fly conditions. Consider throwing a double dry rig in the Park this time of year, leading with a larger, more buoyant bug like a #10-12 stimulator, #10-12 chubby chernobyl, or #10-12 parachute or foam hopper, and trail with a small black beetle or ant in #16-18, an elk hair caddis in #14-16, or virtually any small emerger or cripple in #16-18 on 14-16" of 5x tippet. Dry droppers with small bead head nymphs are always effective in the park, too, as can be small streamers on the strip or swing on cloudier days if you're feeling like switching it up. High lakes in the park continue to fish great on beetles, ants, midges, leeches, caddis, and attractor dries like Hippie Stompers and 409s. Remember that fish in the park are usually more picky about a good drag-free drift and a good approach than they are about flies.

The Ultimate Fly Fishing Report
Casting a fly in a tranquil mountain stream, feeling the tug on the line, and holding a beautiful rainbow trout makes us feel alive and intensely connected with nature. Fly fishing is our way of life and we are blessed with hundreds of nearby rivers and streams just a short distance away from Boulder. From the swift spring waters of the Clear Creek to the meandering bends of the South Platte, it's critical to consider fishing conditions in advance and prepare accordingly. We rely on our experienced guides who venture into the wild to let us know which rivers favor fly fishing, where fish are biting, and which fly patterns are most effective. Planning a successful fishing trip also requires knowledge of stream flows at various river points and an accurate weather forecast for a given destination. At Rocky Mountain Anglers, we are dedicated to providing all avid anglers with detailed and timely information about hatches, water, and weather conditions. So before you head out the door on your next fishing adventure, visit our web site to find valuable information that will prepare you for a successful trip.
